Monarda Plant named &#39;Balbalmose&#39;

ABSTRACT

A new and distinct cultivar of  Monarda  plant named ‘Balbalmose’, characterized by its deep rose-colored inflorescences, dark green-colored foliage, good powdery mildew resistance, and moderately vigorous, upright-compact growth habit, is disclosed.

LATIN NAME OF GENUS AND SPECIES OF PLANT CLAIMED

Monarda didyma

VARIETY DENOMINATION ‘Balbalmose’ BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Monarda plant botanically known as Monarda didyma and hereinafter referred to by the cultivar name ‘Balbalmose’.

The new cultivar originated in a controlled breeding program in Guadalupe, Calif. The objective of the breeding program was the development of Monarda cultivars that are early flowering, have good powdery mildew resistance, and a compact growth habit.

The new Monarda cultivar is an irradiation-induced sport of Balmy Purple ‘Balbalmurp’, U.S. Plant patent application No. 13/987,860, characterized by its dark purple-colored inflorescences, dark green-colored foliage having good powdery mildew resistance, and moderately vigorous, upright-compact growth habit. The irradiation occurred on May 2011. The new cultivar was discovered as a side shoot and selected during September 2012 in a controlled environment in Guadalupe, Calif.

Asexual reproduction of the new cultivar by terminal stem cuttings since September 2012 in Guadalupe, Calif. and Elburn, Ill. has demonstrated that the new cultivar reproduces true to type with all of the characteristics, as herein described, firmly fixed and retained through successive generations of such asexual propagation.

SUMMARY OF THE INVENTION

The following characteristics of the new cultivar have been repeatedly observed and can be used to distinguish ‘Balbalmose’ as a new and distinct cultivar of Monarda plant:

1. Deep rose-colored inflorescences;

2. Dark green-colored foliage;

3. Good powdery mildew resistance; and

4. Moderately vigorous, upright-compact growth habit.

Of the many commercially available Monarda cultivars, the most similar in comparison to the new cultivar is the parent Balmy Purple ‘Balbalmurp’, U.S. Plant patent application No. 13/987,860. However, in side by side comparisons, plants of the new cultivar differ from plants of ‘Balbalmurp’ in at least the following characteristics:

1. Plants of the new cultivar have an inflorescence color different from plants of ‘Balbalmurp’; and

2. Plants of the new cultivar have a filament color that is different from plants of ‘Balbalmurp’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs show, as nearly true as it is reasonably possible to make the same in color illustrations of this type, typical flower and foliage characteristics of the new cultivar. Colors in the photographs differ slightly from the color values cited in the detailed description, which accurately describes the colors of ‘Balbalmose’. The plants were grown in one-gallon containers for approximately two months in a greenhouse and two months outdoors in Elburn, Ill. Plants were given one pinch prior to transplant and one pinch two weeks after transplant.

FIG. 2 illustrates a close-up view of an individual inflorescence of ‘Balbalmose’.

DETAILED BOTANICAL DESCRIPTION

The new cultivar has not been observed under all possible environmental conditions to date. Accordingly, it is possible that the phenotype may vary somewhat with variations in the environment, such as temperature, light intensity, and day length, without, however, any variance in genotype.

The chart used in the identification of colors described herein is The R.H.S. Colour Chart of The Royal Horticultural Society, London, England, 2007 edition, except where general color terms of ordinary significance are used. The color values were determined in July 2014 under natural light conditions in West Chicago, Ill.

The following descriptions and measurements describe plants produced from cuttings from stock plants and grown under conditions comparable to those used in commercial practice. The plants were grown utilizing a soilless growth medium in one-gallon containers for approximately two months in a greenhouse and two months outdoors in Elburn, Ill. Plants were given one pinch prior to transplant and one pinch two weeks after transplant. Greenhouse temperatures were maintained at approximately 45° F. to 65° F. (7.2° C. to 18.3° C.) during the day and approximately 35° F. to 45° F. (1.7° C. to 7.2° C.) during the night. No supplemental lighting was provided. Measurements and numerical values represent averages of typical plants.
